Be forewarned that if you go to pick them up that you might not like the conditions they are in. When I saw them last summer they were in what looked like a 180g, possibly a 220g. The fish did look healthy though.
Assuming you're getting on the TP at the Philly exit and then coming up 476 you're looking at ~1.5hrs. Give or take a little depending on traffic and how fast you drive.
